B.L.Z.BUB Posted March 7, 2011 Report Share Posted March 7, 2011 (edited) So is the part number in their catalogue wrong? Because the capacitor/condenser thay gave me is wrong too. Man I wish I could open their catalogue on the web site. Ill give it another go. And yeah I'll go electronic on the 5K (for some reason it has a points dizzy?). Just need to make the 4K manageable until then. Edited March 7, 2011 by blzbub666 Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted March 7, 2011 Report Share Posted March 7, 2011 Finally got the catalogue open. There are two part numbers One for Bosch And one for Bosch made for Nippondenso. Bosch obviously make a replacement dizzy with different parts. Quote Link to comment Share on other sites More sharing options...
Twinky Posted March 7, 2011 Author Report Share Posted March 7, 2011 I don't think many 5k's had electronic dizzys but the 7k's definately did. When I got my 5k it came with points dizzy. Quote Link to comment Share on other sites More sharing options...
Felix Posted March 7, 2011 Report Share Posted March 7, 2011 Pretty sure from memory the Bosch dizzys use GB534 points (same as most holdens). Can't remember the p/n for the Bosch condenser. What dizzy do you have, Bosch or Nippondenso? Got a pic? Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted March 7, 2011 Report Share Posted March 7, 2011 Must be nippondenso as the Bosch parts don't fit. Quote Link to comment Share on other sites More sharing options...

Old fella Posted March 7, 2011 Report Share Posted March 7, 2011 G`day Reed, these are what I found in an old Bosch 4K-C dizzy in the scrap heap. I`ve got some brand new ones somewhere but where is the problem. Cheers. Quote Link to comment Share on other sites More sharing options...
B.L.Z.BUB Posted March 8, 2011 Report Share Posted March 8, 2011 (edited) Yeah, that's the points set I need. I'll get them to replace the ones they gave me. EDIT: Cheers Trevor I just stole that pic so I have something to show them. Edited March 8, 2011 by blzbub666 Quote Link to comment Share on other sites More sharing options...
Andy43 Posted March 9, 2011 Report Share Posted March 9, 2011 (edited) If you use bosch points get the GB 752 points, There heaps better than the GB 534 They were designed for the XU1 and fit a bosch 3k / 4k dissy. They have a higher spring pressure so less chance of point bounce. I like to set the points to the lower limit, in the case of 3k about 16 thou, This gives the coil a greater charge time.

Does this mean its the nipon denso one? or the aftermarket Bosch one ? and that said - what part numbers am i meant to be chasing down then??

neil Posted November 12, 2011 Report Share Posted November 12, 2011 try replacing the condenser. back in the day of points i was reminded by my dad that the points have a protective coating on them similar to what you have to clean off new brake rotors. try taking them out and hit them lightly with some 2000 grit and then a little carby clean on a cloth. the 2000 wont damage the new points considering its finer than a points file. this is something i always did when installing new points on my 4k. other tips running a 100% standard 4k stock point gap ngk bp5es set to 1.2mm and 11deg timing gt40 coil being the only modification don't forget to double check and reset the points after a few days as they tend to close up a little after installing new ones. ( has happened to me slightly before, not a major issue but if your trying to get the most out of your 4k then you will want to check) remember to set your timing again!

WA_TRD_83 Posted November 12, 2011 Report Share Posted November 12, 2011 try replacing the condenser. yup, I've replaced the condenser thats attached to the dizzy. although today I noticed one similar thats attached to the coil? does anyone know if this is the same part?
